Subject: [PATCH 2/6] dt-bindings: PCI: qcom-ep: enable DMA for SM8450

Qualcomm SM8450 platform can (and should) be using DMA for the PCIe EP
transfers. Extend the MMIO regions and interrupts in order to acommodate
for the DMA resources. Upstream DT doesn't provide support for the EP
mode of the PCIe controller, so while this is an ABI break, it doesn't
break any of the supported platforms.

Fixes: 63e445b746aa ("dt-bindings: PCI: qcom-ep: Add support for SM8450 SoC")
